Can y’all please find the constant ratio for each

Step-by-step explanation:

1.

c.r.=10.5/10=105/100=21/20

or 10.5/10=1.05

2.

c.r=9/27=1/3

3.

c.r.=(3/4)/1=3/4

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
